<![CDATA[Penelitian eksperimen ini bertujuan untuk mengetahui efektivitas dan efisiensi model pembelajaran terpadu yang memang sudahdianjurkan pemerintah untuk diterapkan dalam Kurikulum Tingkat Satuan Pendidikan (KTSP). Pembelajaran IPA terpadu tipeintegrated dipilih dengan menggabungkan materi dari tiga mata pelajaran, yaitu fisika, biologi, dan geografi dalam satu tema yaitucahaya. Populasi adalah kelas VIII semester 2 yang berjumlah 5 kelas. Pengambilan sampel dengan teknik random sampling.Hasilpenelitian menunjukkan bahwa hasil belajar kelompok kontrol lebih baik daripada kelompok eksperimen tetapi rata-rata nilai keduakelompok sudah melebihi Standar Ketuntasan Belajar Minimal (SKBM) sekolah, yaitu 70. Ketuntasan klasikal kedua kelompokjuga sudah dicapai, bahkan ketuntasannya lebih dari 90%. Efektivitas model pembelajaran IPA terpadu tipe integrated tidakberbeda secara signifikan dengan model pembelajaran IPA terpisah tetapi lebih efisien dalam waktu pembelajaran. Jadi, modelpembelajaran terpadu layak diterapkan dalam pembelajaran dengan beberapa pembenahan.ÃÂ This experiment research aimed to find effectiveness and efficiency of integrated science learning model which is suggested by thegovernment to be applied in Kurikulum Tingkat Satuan Pendidikan (KTSP). The learning of integrated science was chosen bycombining the materials of three subjects: physics, biology and geography in a theme, which is light. The population of the researchwas the VIII grade second semester student consisting of five classes and sampling technique used was random sampling. Theresult of the research showed that learning achievement of control group was better than that of experiment group, but the averagevalue of both groups was more than minimal learning achievement standard of the school which was 70. Classical learning-masteryof both groups which was 90% has also been reached. Although the effectiveness of integrated science learning model was notdifferent significantly with separated science learning, the time consumed by the integrated model was more efficient. So, theintegrated science learning model is suitable to be applied in the lesson with several improvements.Keywords: Effectiveness; efficiency; integrated science learning]]>
